Brain, pelvis, hands and feet don't lie - and five recent studies of Australopithecus sediba, a primitive hominin that existed around the same time early Homo species first began to appear on Earth, suggest this ancient relative and its primitive and modern, human-like traits, make it the best candidate for an ancestor to the Homo genus.
The discoveries are casting doubt on some long-standing theories about human evolution, including the notion that early human pelvises evolved in response to larger brain sizes. And there is also some new evidence suggesting that Australopithecus sediba may have been a tool-maker.
In football, if you are a lineman, you are going to give and take a lot of hits - but running backs really get punished.
Whenever a popular television health claim makes its way into the media, some skepticism is in order. A decade-long war on "trans fats", including outright bans in some areas, was not based on science or objective evidence.
Geobacter can clean up uranium but a new study documenting how microbes generate electricity while cleaning up nuclear waste and other toxic metals could mean a big benefit for contaminated sites in the future.
Identifying the Geobacters' conductive pili (nanowires - hair-like appendages found on the outside of Geobacters) as doing the bulk of the work is a new revelation. The nanowires also shield Geobacter and allow the bacteria to thrive in a toxic environment.
In 2009, UK drugs advisor Dr. David Nutt was relieved of his duties due to controversial views on the harmfulness of different drugs and the lack of evidence behind current drug policy.
Various claims were that this was politically motivated and concern was that scholarly research such as Nutt's should not be subject to political attack.
Agreed, but a new article in Addiction says the attack was justified because Nutt's work on the harmfulness of drugs is scientifically flawed.
Almost half of recreational runners drink too much fluid during races, showing many athletes hold unscientific views regarding the benefits of different hydration practices .
Expert guidelines recommend runners drink only when thirsty but a recent Loyola survey found that 36.5 percent of runners drink according to a preset schedule or to maintain a certain body weight and 8.9 percent drink as much as possible.
